UEL SYSTEM
20 DIAGNOSTICS
• This system indicates any error on both the input and
output signals.
• As the errors are stored, they are indicated even if
they are no longer present but occured during engine
running (“yellow” errors); the ECU is not “reset” by
removing the key OFF contact.
• When a current error (“red” error) is resolved, it will
then be displayed by the ECU as a “yellow” error.
• The ECU is not automatically reset after a certain
number of ignitions, as was the case for the 1.6, but it
must be reset using the specific software.
• If a signal from a sensor is interrupted, the ECU
acquires its average value. This allows the motorbike
to be used (even if it is not in perfect working condition).
• The following circuits can be diagnosed:
1)Throttle valve potentiometer;
2)Absolute pressure sensor (inside the ECU);
3)Oil temperature sensor;
4)Air temperature sensor;
5)Battery voltage (indication for V<8 and V>16);
6)Injectors 1 and 2;
7)Coil 1 and 2 primary winding;
8)Fuel pump relay;
9)ECU;
10)Timing sensor;
11)Electronic revolution counter
• When the ignition key is turned to the OFF position,
the ECU is no longer powered. It can therefore be
diconnected immediately.

ESETTING THE
ECU
The ECU resetting procedure is very simple and is the
following: open the “Active Test” page and click on the
erase key using the mouse. If the “PASS” status appears,
the operation has been successful, if not, there are current
errors present which can be viewed on the page:
